Gas leaking into intake

I have a model 59 carb on my '36 and when the engine is not running, the carb is leaking into the intake (at a pretty good clip). Could this be the power valve leaking by? Thanks, Ed
 
that is the sign of a leaking power valve, the only other thing that causes that is a high float setting and the gas will boil out of the carb when the engine is shut down hot
